This feature got lost with new auto-track API, Added it back by extending frame accessor class. This isn't really a frame thing, but we don't have other type of accessor here. Surely, we can use old-style API here and pass mask via region tracker options for this particular case, but then it becomes much less obvious how real auto-tracker will access this mask with old style API. So seems we do need an accessor for such data, just matter of finding better place than frame accessor.
